The XF-104, Lockheed Model L-246, was designed by “Kelly” Johnson of the famed Skunk Works. 173 F-104 A models were built. It was a high-performance day and night fighter powered by an axial-flow, turbojet engine with afterburner. The F-104 A is a single place aircraft, designed for cruise at high subsonic speeds and combat at high supersonic speeds. Notable features of the aircraft include extremely thin flight surfaces, short straight wings with negative dihedral, hydraulically powered ailerons and horizontal stabilizer. The wings, with leading and trailing edge flaps, have a boundary layer control system which is used in conjunction with the trailing edge flaps to reduce landing speeds. A drag chute is installed to reduce landing roll.
